1 Claim.

This invention relates to a compact filling machine, for filling cushions, pillows, mattresses, and the like with fibrous materials such as cotton, hair, excelsior, as well as inner spring units.

An object of this invention is to provide a filling machine designed to insert filling material in a cushion casing, and the like, by means of a reciprocable plunger-head which feeds the filling material into the casing, and is then withdrawn to its original position.

Another object of this invention is to provide a filling machine having a two tier frame, comprising a lower tier having two speed reducing gears and jointed linkage, and an upper tier having plunger actuating foldable linkage for actuating a plunger-head, the linkage being arranged to operate wholly within the range of motion of the plunger-head, to thereby conserve fioor space.

In prior filling machines of this character a long driving member was used for actuating the plunger-head, and. in such arrangement the driving member extended outwardly from the machine a distance at least equal to the length of the filling portion of the machine. This was a disadvantage in that it increased the overall length of the machine. In the disclosure herewith, we have provided a filling machine which reduces the fioor space to a minimum, and utilizes a more simplified mechanism.

With the above and other objects in view, the invention will be hereinafter more particularly described, and the combination and arrangement of parts will be shown in the accompanying drawings and pointed out in the claim which forms part of this specification.

Reference will now be had to the drawings, wherein like numerals of reference designate corresponding parts throughout the several views, in which:

Figure 1 is a top plan view of the filling machine, with the plunger-head in retracted position.

Figure 2 is a top'plan view of the filling machine, with the plunger-head in operating position.

Figure 3 is a rear elevation of the filling machine.

Figure 4 is a cross-sectional view taken on line 4-4 in Figure 3.

Figure 5 is a front elevation of the receptacle portion of the filling machine, looking in the direction of the filling end of the filling machine.

In the illustrated embodiment of the invention, the numeral III indicates a. filling machine porting member [8 is secured to the longitudinal 7 frame members I3. Two worm gears [9, are freely rotatably mounted on stub shafts 2i) suitably fixed to the supporting member I8.

The gears I9 are positioned in spaced-apart relation and are in meshed relation with an elongated worm 2|. The worm 2| is rotatably supported in bearings 22 which are secured to crosswise extensions 23 of the supportingmember I8. A pulley 24 is secured at one end of the worm 2| and carries a belt 25 which is in engagement with a pulley 26 carried by a motor 27. The motor is secured to one of the frame members I3.

Extending from each worm gear I9 is a boss 29. Mounted in each boss 29 is a stub-shaft 30 connected by a link 3| and a pin 32 to an arm 33 having one end fixed to' an upright shaft 34. Each shaft 34 is rotatably mounted at its lower end in a bearing 35 fixed to a cross-member It. At its upper end, each shaft 34 is rotatably mounted in a bearing 36 fixed to a cross-plate 31. The plate 31 is supported at each end on a channel 38 fixed to a cross-member I6.

As shown in Figure 4, it' will be seen that rotation of the motor 21 will cause the worm shaft 2| to rotate the worm gears I9 in opposite directions. The gears I9 reciprocate the links 3| which oscillate the arms 33 and this causes the upright shafts 34 to oscillate in opposite directions.

As shown in Figures 1 to 3 inclusive, an adjustable receptacle 4|] is mounted on the upper surface of the frame II. The receptacle is of a length which causes an end portion thereof to extend beyond an end wall 4| of the frame I I. The extending portion 42 permits a portion of a pillow casing or the like to be secured thereto prior to the filling operation. The receptacle 4!] is mounted horizontally on the frame II and both ends of the receptacle are normally open.

As shown in Figures 1 to 3 inclusive, a plungerhead 43 of rectangular form is slidably mounted inside the receptacle 48. Secured to each upright shaft 34 is a right-angular crank 45 having a pin 46 at its free end. A link 41 is connected by the pin 46 to the free end portion of the crank 45 at one of its ends. At the other end, the link 4'! is connected by a pin to a bearing plate 5| suitably fixed to the plunger-head 43.

As shown in the top plan views in Figures 1 and 2, oscillation of the shafts 34 causes the cranks 45 to move the links 41 and the plungerhead 43 the inoperative .qsition shown in Figure 11 t e Q 'ii ili imi' in F ure 2. During the movement of the plungerhead 43, it is guided by an elongated key 48 centrally positioned in the receptacle 40.

It is to b noted that in the-preferred embodiment shown, there are two sets of folda'bly linked drive members 55, each set consisting f a right.- 7

angular crank 45 and its connected link 41., ,Qne set of foldably linked drive member 55 is positioned at a higher elevationthan the other set to permit the two sets to move towards each other in overlapping relation without interfere 0. a 99 p o de fo travel o the lunge -r ed.

4 the cover in frictional engagement on the receptacle 40. A foot control switch (not shown) supplies electric current to the motor. The operator steps on the switch thereby supplying current to the motor, and causes the motor pulley to rotate. This rotation causes the foldably linked drive members 55 to move the plungerhead 43 into the receptacle 4!] and :to force the filling material outwardlyl-nto the cover of the cushion. The cushion cover is gradually forced off the receptacle while it is being filled With the filling material.

, Upon mmpletion of the forward movement of the plunger-head 43, the operator removes his ,foot from the electric foot switch and raises the receptacle covers 59, 59 preparatory to filling another cushion cover.

It is to be noted that the frame portion It at the filling end of the machine ID as shown in Figures 1, 2 and 5 is at a lower elevation than the main portion defined by the cross members l5, I6. There is thu provided an operating space below the filling end of the receptacle 40 for freedom of movement of the operators hands when he secures a cushion cover to the receptacle 4D.

It is also to be noted that while we have shown.

two sets of foldably linked drive members, each operating independently, that we may use an interconnected linkage known as the pantograph.v

In accordance with the patent statutes We have described and illustrated the preferred embodiment of our invention, but it will be understood that various changes and. modifications can behaving an end portion. extending beyond. said.
